Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx +)K yG  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm We*c_;@<  
Type: Double Bounces dCM*4B<  
The '****' denotes a possible internal focus 6u v'{  
RMS is the RMS spot radius on axis at the primary wavelength. y2Z1B2E%f  
RMS values of 0.00 indicate that an accurate RMS )Z2t=&Nw  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is {p@uj_pS  
non-rotationally symmetric or uses non-standard surfaces.
